Specification of Letters Patent N 0. 10,053, dated September 27, 1853.

T0 alt whom it may concern:

Be it known that I, IVILLIAM ZIMMERMAN, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful centrifugal and gravitating smut-machine for cleaning and scouring grain, &c., hulling rice, pear-ling barley, &c.; and I do hereby declare that the same is described in the following specification and drawlngs.

The nature of my invention consists of a series of two or more stationary cones, with one two or three or more revolving cones placed alternately between the stationary cones; the insides or outsides of part or both sides of part or all the cones may be furnished with roughened surfaces, of such a form or kind as will perform the service required.

T 0 enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation, referring to the accompanying drawings in which the same letters indicate like parts in each of the figures.

Figure 1 is an elevation of the machine with some portions broken away to show others. Fig. 2 is a plan of the top. Fig. 3 portions of cones. Fig. 4 portion of a cone with different surface. Figs. 5 and 6, sections of parts of cones. Fig. 7 a section showing the relative position of the cones.

In the accompanying drawings A is a base provided with a step for the lower end of the shaft B, the upper end of which shaft turns in a hole in the cross C which is supported by the parts E E &c. fastened in the base A. I make some scores in the posts E for the lugs which support the stationary cone IV one of the lugs being represented in the score at G Fig. 1.

The stationary. cones may be made of wrought or cast metal with protuberances on a roughened surface upon one or both sides. If made of wrought metal they may be perforated so as to leave a rough bur around the holes upon one or both sides of the metal; or there may be pieces fastened upon one or both sides with roughened edges; or the metal may be swayed or bent so as to form ridges or protuberances upon one or both sides, with indentations upon the opposite sides corresponding to them, as shown at H H Fig. 3. Or if the cones are made of cast metal there may be ridges on one or both sides, or ridges protuberances and cavities upon one or both sides, or made rough in such form as fancy or experience may deem most desirable; and a portion or all of one or both sides of part of the same may be left smooth; and the lower stationary cone may be perforated or made of wave wire so as to allow the dirt and refuse matter to pass through while the grain descends into the trough I which has a perforated bot-tom so as to separate such refuse matter as may fall into it, with the grain, from the lower end of the lower stationary cone which is left open for the grain to escape.

There are rims J fastened to the top of the stationary cones to support the next stationary cones in the series above them. These rims J J may be perforated alsothat part of the succeeding cones which comes above the rims so as to allow the air to carry any refuse matter through the cones or rims and separate it from the grain during the process. There should be some lugs upon the outside of the stationary cones with a cover K; with a hopper L fastened to it; this cover is supported by lugs which are fastened to it and rest upon the rim J as represented at M. The edge of this cover is serrated and the points N N are turned down so as to come just within the rim J so that, that portion of the grain which falls from the hopper onto the rotating disk 0 will pass over the roughened surface of the disk and be thrown out against the cone P being acted upon by the points Q Q upon the disk 0, and the points N N above mentioned as it passes between them. A part ofthe grain put in the hopper L passes through the tube R around the shaft, and through the hole S in the disk 0 and falls upon the perforated ventilating box T which forms the connection between the shaft B and the revolving cone U as represented Fig. 7.

The ventilating box T may be made conical with the small end up if preferred, and the grain that falls upon it is carried by centrifugal force onto the cone V, and up inside the cone and passes between the upper edge of the cone and the disk 0 as represented in Fig. 7, where it mingles with the grain that passes off of the top of the disk, and the whole descends between the cones V and P and falls upon the second rotating cone and is carried up inside by the centrifugal force of the rotary motion, and is acted upon by the roughened surface of the cone V and also the cone P if it is set near enough to it and passes over the edge of the cone V against the rim J and cone WV and descends between the cones V and V being acted upon by the under side of the cone V if it is set near enough to WV to permit it to do so, and passes out of the cone W into the trough I which conducts it away from the machine. The revolving cones may be constructed in any of the forms and of any of the materials enumerated and described of which the stationary cones might be made or otherwise, or of other materials, or may be made plain or otherwise and pieces of metal may be per forated by being punched one or both ways, and fastened to the inside of the cone as represented in Fig; 5, so as to leave a space between the piece fastened onto the cone, and the cone, for the grain to pass up and be operated upon, and as the spaces under the pieces will be narrower near the shaft than at the circumference, there may be more space left between the piece and the cone, at the narrow end; and the grain may pass up, on the top of the piece as well as under them at the same time. And to sepa rate the garlic or for other service, a piece of leather or other material may be driven full of nails, and fastened upon the revolv- I ing cone with the points of the nails sticking up as represented at X Fig. 1 and the edge is shown in Fig. 6.

It is obvious that a machine may be constructed wit-h as many stationary and revolvingcones as may be expedient or deslrable, so as to contmue the operation of scouring the grain until it is perfected or carried to such a degree of perfection as may be desirable for the purpose intended.

Motion may be communicated to the shaft by applying a pulley or gear above the cone or below as may be most convenient; and a fan may be arranged to blow the smut from the grain as it passes from the cone into the trough I and also to fan it as it passes from the trough I; and it is desirable the shaft B may be made hollow and left open at one end, and perforated so as to supply air to such portions of the cones as may be necessary.

I contemplate that my machine may be I modified in various ways to suit the circumstances in which it is to be used without departing from the principle of my invention.

What I claim as my invention and desire to secure by Letters Patent in the abovedescribed machine for cleaning and scouring grain, hulling rice, pearling barley hulling buck wheat or otherwise operating 2 upon grain seed etc., is

A series of two or more stationary cones, with one, two or three or more revolvlng cones placed and operated alternately be- .tween the stationary cones; the insides or .outsides of part, or both sides of part or all the cones being furnished with roughened surfaces, of such a form or kind as will perform the service required substantially as described.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.

WILLIAM ZIMMERMAN.
